Latest Messenger RNA Stories
MicroRNAs (miRNAs) are endogenously encoded RNAs that regulate the stability or translation of mRNA molecules, and emerging research suggests that they have diverse roles in normal physiology and disease.
New research has shown that a protein does something that scientists once thought impossible: It unfolds itself and refolds into a completely new shape.
Scientists from the Florida campus of The Scripps Research Institute have identified a series of intricate biochemical steps that lead to the successful production of proteins, the basic working units of any cell.
In the July 6 issue of Cell Stem Cell, researchers at the University of California, San Diego School of Medicine describe how human epidermal progenitor cells and stem cells control transcription factors to avoid premature differentiation, preserving their ability to produce new skin cells throughout life.
Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics that DNA consists of only four bases.
How do we build a memory in the brain?
Human cells are thought to produce thousands of different microRNAs (miRNAs)—small pieces of genetic material that help determine which genes are turned on or off at a given time.
Our genes control many aspects of who we are — from the colour of our hair to our vulnerability to certain diseases — but how are the genes, and consequently the proteins they make themselves controlled?
It had long been assumed that the human sperm cell’s mission in life ended once it had transferred its freight of parental DNA to the egg.
